GEORGE I-I. HOLGATE, OF PHILADELPHIA, PENNSYLVANIA.

CARBURETER.

Application led June 18, 1906.

To all whom 'it may concern:

Be it known that I, GEORGE H. IIoLGATE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Carb'ureters, of which the following is a specification.

My invention relates to improvements in carbureters and particularly to certain new and useful improvements lin a carbureter for which Letters Patent of the United States were issued to me on the twenty-seventh day of February 1906 No. 813,796.

The object of my invention is to construct a carbureter which will be adapted for heating purposes.

A further object of my invention is to so construct a carbureter that a very low grade of hydro-carbon oil may be used and thereby produce a heat at a minimum cost. 'lo do this I provide means for heating the chamber containing the oil so that a gas of great heating power will be produced.

In carrying out my invention I employ a chamber containing an absorbent for the oil, a lamp for preheating the gas in said chamber, a central supply-pipe having a burner thereon suitable for heating and cooking purposes, means for admitting air to said chamber, means for regulating the admission of the air to regulate the quality of the gas as it passes to the burner, means for admitting air to said supply-pipe, an ignition burner located in said supply-pipe immediately above said chamber for the preliminary heating of the burner; also a housing or Aframe for the carbureter so that the same may be used as a gas stove for cooking and heating purposes, these together with various other novel features of construction and arrangements of parts which will be hereinafter fully set forth and claimed.

Referring to the accompanying drawings z-F igure 1. is a vertical sectional view of my improvedcarbureter applied as a gas stove; Fig` 2. is a horizontal sectional View as on line 2-2 Fig. 1 Fig. 3. is a horizontal sectional view as on line 33 Fig. 1 ,1 and, Fig. el. is a horizontal sectional view as on line #4 Fig. 1.

In the drawings 1 represents a chamber which is cylindrical in form, having a top 2, a bottom 3; and a central tube 4 secured at one end to the top 2, and its other end extending to Within a short distance above the bottom Specification of Letters Patent.

Patented July '7, 1908.

Serial No. 322,159.

.3, said tube 4 is-provided with openings at both ends into which tightly A[its a rotatable sleeve 5. The sleeve adapted to rotate around a supply-pipe said sleeve 5 Yfitting closely over the same. 'I`he supply-pipe is rigidly held to the bottom 3 by a square bolt 7 which prevents the supply-pipe from turning. The sleeve 5 and the supply-pipe 6 are provided with apertures 8 and 9 respectively which may be madeto register by turning the sleeve 5 by means of the handle 10 on the plate 11 secured to the sleeve 5. 'lhe said plate 11 is provided with apertures 13, and the top 2 of the chamber is provided with apertures 14 which said apertures 13 and 14 are brought into register when the. handle 1() is turned to a position to open the apertures S and 9 in the sleeve 5 and the supply-pipe 'lhe chamber 1 contains absorbent material preferably formed in hollow cylinders 15, which are of dill'erent diameters so that the same may be nested, a space being left between said cylinders for the free passage of air. l'lhe cylinders are held. in vertical position by perforated screens 1G and 17 so as to provide air spaces 1S and I9 above aud below the absorbent cylinders. The absm'bent may be of any material such as plaster-ofparis, felt, sponge, or any other material capable of absorbing a liquid, but I prefer to use a composition of plastcr-of-paris and an infusorial earth.

The absorbent n'iaterial is charged with gasolene, benzin, naphtha, petrol or other hydro-carbon oil.

A screw cap 20 as shown in Fig. 'l is provided to cover an aperture formed in the top '2 of the chamber through which the chamber may be filled. A tube '21 is also provided at the lower portion ol' said chamber to draw oll any excess oil which may remain in the chamber after the absmbent material has become thoroughly saturated.

Airis admitted to the chamber 1, through the openings 13 and 14 in the top 2, the air will then become charged with h vdro-carlmn as it comes in contact with the absorbent material and be converted` into a gas.

Directly above the chamber 1, vl provide an ignition-bluner in the supply-pipe 6, consisting of a wire gauze cap 25. The supplypipe hasl an aperture 26 formed therein which is closed by a sleeve 27 encircling the supply-pipe. rlhe sleeve 27 has an opening 28 corresponding with the opening 26 in the supply-pipe, and the said openings may be brought into register by turning the sleeve 27, whereby access may be had to the wire gauze cap 25.

By bringing a lame in close proximity with the wire gauze cap 25 in the supplypipe a vacuum will be created in the supplypipe which will cause the gas to be drawn through the apertures 8 and 9 from the space 1Q formed at the lower portion of the cham ber 1, and the gas will continue to flow and burn at the cap 25.

The object of having the ignition-burner is to preheat the main burner 30, the latter is such a great distance from the carbureter that it cannot be lighted by a iiame brought in contact with the same without preheating to create a draft which will draw the to the burner 30. lt is desirable to malre the supply-pipe as long as possible so that the gas and air will become thoroughly mixed.

After the ignition-burner has been burning a few seconds the handle 10 is turned t0 close the air inlet apertures 13 and .14 in the chamber, and the apertures` S and 9 in the supply pipe 6, thus the supply of gas is shut 0H' and the flame at the ignition-burner will be extinguished. The sleeve 27 is then turned so as to close the aperture in the supply-pipe 6 at the ignition-burner and the handle 10 is turned to reopen the said apertures 13 and 14 in the chamber and the apertures 8 and 9 in the supply-pipe. By immediately applying a 'flame to the main burner 30 the gas from the carbureter will burn at said burner 30.

A casing 35 is provided below the chamber 1. to receive a lamp 36 which is used to heat the chamber 1 and. thereby preheat the gas and increase the quality of the same so that very low grade of oil may be used to saturate the absorbent material. rlhe casing 35 l is provided with a door 37 so that the lamp I 36 will be accessible.

To regulate the quality of the gas passing to the burner 30 I provide means for admitting air directly to the supply-pipe 6 through openings 4() in the supply-pipe communicating with the tube 4 which has openings 42 at the top of the same. The openings 40 in the supply-pipe are closed by the sleeve 5 having openings 41 which register with the openings 40 in the supply-pipe. The openings 42 at the top of the tube 4 are closed by the plate 11V having openings 43 which register with the same. These openings are arranged so that the same will open when the handle 1() is turned to close or reduce the size of the openings 1?, and 14 in the top of I the chamber 1 and also the openings 8 and 9 l in the lower portion of the supply-pipe 6. Thus if the gas is too rich with carbon the supply of air to the chamber 1 may be reduced and at the same time air is admitted directly to the supply-pipe through the openings 40 and 42, or when the gas is low in carbon the openings 13 and 14 may be lfully opened and. the openings 4() and 42 entirely closed so that all the air admitted will pass through the chamber 1.

The carbureter is held in a housing consisting of a frame 50 supported by legs 51. which are adapted to rest on the iiocr. Around this frame a casing 52 having a door 53 through which the carbureter may be removed. The casing 52 is provided with a top 54 which is made in the l'orm now generally in use in gas stoves.

Having thus describedA my invention I claim and desire to secure by Letters Patent l. ln a carbureter, the combination of a chamber, absorbent material in said chamber, a supply-pipe, a burner at the top of said supply-pipe, an ignition-burner in said supply-pipe located between said chamber and said first mentioned burner, substantially as described. 2. ln a carbureter, the combination of a chamber, absorbent material in said chamber, a supplypipe, a burner at the top of said supply-pipe adapted for heating purposes, an ignition-burner in said supply-pipe located between said chainber and said 'lirst mentioned burner, and means for heating said chamber, substantially as described.

3. In a carbureter, the combination of a chamber, absorbent material in said chamber, a supply-pipe rigidly secured in said chamber, said supply-pipe having apertures opening into said chamber, apertures formed in said chamber to admit air thereto said supply-pipe having apertures formed therein for admitting air thereto, means for opening or closing said apertures, a lamp for heating said chamber, a burner at the top of said supply-pipe, a wire gauze cap in said supply-pipe located adjacent said chamber, said supplypipe having an opening' 'formed therein near said cap, a sleeve Al"or covering said opening, a frame to support said chamber, a casing and a top on said casing, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE H. HOLGATE.
